Sorry I haven't been on this app in a while. I have a question about food allergies in toddlers. Yesterday I noticed a hive rash on my 2 year olds behind when I was changing her pull up. The only different food I had given her was dried pineapple. I gave her some antihistamine and it cleared up. Has anyone had a baby or toddler allergic to pineapple?
